About one-third of the 3,700 described trombiculid species in the world (Acari: Trombidiformes Trombiculidae sensu lato) are represented by types in the Smithsonian Institution collections. The catalog of primary and secondary type specimens (holotype, paratype, syntype, lectotype, and paralectotype) included 1,026 chigger species of which 645 were holotypes, 782 were paratypes, 69 were syntypes, 19 were lectotypes, and 16 paralectotypes on more than 2,560 slides. Most were larvae and only 9 were deutonymphs and/or adults.
